add disk_domain disk

add disk_domain disk

Function

The add disk_domain disk command is used to add disks to a disk domain.

Number of disks that you want to add to a disk domain. When you use this parameter with parameter disk_type=?, the system automatically adds disks of specified types and quantity to a disk domain. If you specify this parameter, you cannot specify parameter disk_list=?.

The value is an integer ranging from 1 to 2147483647.

disk_type=?

Type of a disk that you want to add to a disk domain.

The value can be "SAS", "NearLine_SAS", "SSD", "SAS_SED", "NearLine_SAS_SED", "SSD_SED", or "SATA", where:

"SAS": SAS disk.

"NearLine_SAS": NL-SAS disk.

"SSD": SSD.

"SAS_SED": self-encrypting SAS disk.

"NearLine_SAS_SED": self-encrypting NL-SAS disk.

"SSD_SED": self-encrypting SSD.

"SATA": SATA disk.

NOTE:

The following describes the disk type supported by each storage tier:

Tier 0 (high performance tier): SSD.

Tier 1 (performance tier): SAS disk.

Tier 2 (capacity tier): NL-SAS disk.

ignore_disk_capacity=?

Whether to ignore the disk capacity.

The value can be "yes" or "no", where:

"yes": ignores the disk capacity.

"no": does not ignore the disk capacity. Check whether the capacity of expanded disks is truncated.

disk_group_id=?

ID of a disk group.

The value is an integer ranging from 0 to 31.

enhanced_data_protection_policy=?

Whether to use the enhanced data protection policy.

The value can be "yes" or "no", where:

"yes": uses the enhanced data protection policy.

"no": does not use the enhanced data protection policy.

The default value is "yes".

Usage Guidelines

If the number of added disks is smaller than the maximum number of disks for a RAID level that maps to storage pools in a disk domain, note the following items:

Create a LUN or expand LUN capacity after data is leveled in the disk domain.

If a thick LUN is created before data leveling is complete, start host services on the LUN after space allocation or formatting.
